Wind and rain test

Wind-Driven Rain Resistance tests are useful to products that are designed for outdoor use in harsh environments. Our services include also icing rain tests in unique walk-in chamber.

Make sure your products can withstand the elements in harsh, wet and windy environments! Wind-Driven Rain tests are useful to products that are designed for outdoor use in harsh environments. For example, in airports, offshore locations, shipping industry and telecommunications, products are often affected by not only severe temperatures, but also strong wind and hard rain. Products designed for such conditions can be tested with our Wind-Driven Rain equipment, capable of wind up to 40 m/s with rain and 67 m/s without rain.

Icing Rain -test
This test is for companies who design products to be used in environments where freezing weather and icing conditions can be expected.
The test is designed by Toptester for outdoor products that need to remain fully functional and operational in conditions where the temperature could drop below zero – resulting in icing. Typical examples of such harsh environments are airports, offshore locations, shipping, telemasts and arctic conditions.

Icing raintests can also provide unique sales argumentation opportunities concerning product quality, reliability and resistance capacity. Also MIL-STD verification is available. Please take a look at this icing rain -video by Suunto.
